Don't use single quotes as quotes in command-line parsing on windows?

[Alexander Belchenko]

Hi all,

Recently John Meinel merged his patch for custom parsing of bzr 
command-line on windows and expanding all globs as it works in the posix 
shell. Simultaneously he introduced support for single quotes as in posix.

In my understanding this will break usual behavior of windows programs, 
because standard windows shell and especially CommandLineToArgv Win32 
API function does not support single quotes in this manner. Especially 
as Martin (gzlist) noted it will break work with filenames which has 
single quote inside:

C:\bzr\bzr\2.1.0b3-win32-shell-completion>echo Be nice; be mean > 
dos_and_don'ts.txt

C:\bzr\bzr\2.1.0b3-win32-shell-completion>python bzr add dos_and_don'ts.txt
bzr: ERROR: No such file: 
u'C:/bzr/bzr/2.1.0b3-win32-shell-completion/dos_and_donts.txt'

I've sent merge proposal to disable support for single quote:

I'm asking for comments or reviews of my patch. If you using windows 
long enough and prefer to keep standard windows behavior -- say so. If 
you want to have support for single quote -- also say so.

Please!

As it noted several times in recent thread about Canonical's plans on 
bzr, there is still accepted community patches and community reviews. 
So, be active if you feel something need to be fixed. I need second 
approve vote for my patch or one disapprove to reject.
